Big Tim,if ever you intend to make a book out of all that background information on songs you collect I'll buy it. The songs come much more alive for me if I read about the background.
As usual I have no local information but a tiny bit I found on the web:
Fair towns of Ireland, 1834 only lists Turloughmore in Clare as a fair town.
And a 'County Clare in 1845' site (http://www.clareweb.com/eolas/coclare/history/gazclare.htm) gives the dates of the Turloughmore fair as follows: Turloughmore, June 8, Sept. 29, and Dec. 12.
